Step 435: Whether the total amount of data stored in the first buffer 310 reaches the first threshold If yes, go to step 440, otherwise, go to step 430 to continue buffering the data in the first buffer 310 following 1293172. Step 440: Store the input data to the second buffer 32. Data storage control The element 331 now stores the input data % to the second buffer class buffer 102. Step: Does the library have the second buffer to request the total amount of data to reach the second threshold? If so, skip to step 45, Otherwise, skip to step _ to continue buffering the data in the second buffer 32. Steps • • Transfer the data stored in the second buffer (4) to the first buffer 31〇 and drive the first buffer 31 to output the storage. In the data therein, the data transfer control unit 332 is activated to start transferring the data stored in the second buffer 320 to the first buffer and the drive, [a buffer 310 outputs the data stored therein to the optical storage device 350. . Step 460 ·· Burning the first, the data output by a fascinating 31G. The optical storage device 350 f burns the data output by the first buffer 310 on the optical disc.

The data storage control unit 331 then stores the input data Din to the second buffer 3, for example. Step 545: Does the total amount of data stored in the first buffer 31 and the second buffer 320 reach a third threshold? If yes, go to step 55, otherwise, go to step 530 or step 54 to continue buffering the data to the first buffer 310 or the second buffer 320. Step 550 transfers the data stored in the second buffer g 320 to the first buffer 31〇. The material transfer control unit 332 transfers the data stored in the second buffer 32A to the first buffer 310. Step 555·• Is the total amount of data transferred to the first buffer $310 reach a fourth critical value? If yes, go to step 560, otherwise, go to step 550 to continue buffering the data to the first buffer 31. Step 560. Output the data stored in the first buffer. The data transfer control unit 332 drives the first buffer 31 to output its stored data. Step 570: Burn the data output by the first buffer 31. The optical storage device 35 烧 burns the information outputted by the first buffer 31 〇 on a disc. Step 575 • Does the beast burning stop? If yes, skip to step · otherwise, skip to step 530 or step 540. Step 580: End. 1293172 Those skilled in the art should be aware that the data burning speed of the optical storage device 350 is much faster than the data generating speed of the multimedia data generating device 340. Therefore, the data burning process of the currently buffered data will be in a pole. In a short period of time, in the embodiment, the first buffer 31 〇 and the second buffer 32 〇 are used as data buffers before the optical storage device 350 starts the beating process, such that The number of joint points can be reduced, and the present embodiment discloses the use of the optimized buffer-H 31G and the second buffer 320 to reduce the number of joint points. Referring to Fig. 5, Fig. 5 is a schematic diagram showing the data buffering state of the first buffer n 310 and the first buffer 32 第 shown in Fig. 3. The threshold value provider 333 provides a first threshold value 以及ι and a second critical mass τΗ2 to the first buffer and the buffer 320, respectively. At the beginning, the multimedia material generating device 340 generates an input data cell at time T0, and then, The data storage control unit 331 buffers the received input data Din to the first buffer 31〇, and the total amount of data buffered to the first buffer 31° reaches two. At this time, the data storage control unit 331 The buffered mi f > ^ is buffered into the first buffer 320, please note that the edge rushes to the first buffer 31 〇 杳 曰 曰 ^ ', so: the ization has not exceeded A threshold value TH1, so the billet transfer control single point, as shown in Figure 5 - will not start to allow data to be written. As shown in Fig. 5, when the total amount of time material reaches the second critical value TH2, the resources of the autumn u-buffer 320 continue to buffer the input data Din, buffered to, and if, the second buffer, please,资料~ buffer 320 data total 1293172 amount will exceed the second threshold value at time τ2 and the miscellaneous transfer control unit 332 will be activated to be stored in the second buffer (four) to the first buffer 310, very Obviously, after receiving the data outputted from the second buffer coffee, the total amount of data buffered to the first balancer 3 i 亦 will also exceed the first critical value Tm at time T2, and similarly, the data transfer 332 The data stored in the first buffer is transferred to the optical sub-device 350. Therefore, the data burning process starts at time = 2 = the storage device 350 burns the first buffer 31 on the optical disc. data. As shown in Fig. 5, the second buffer 32〇 is cleared at time & the total amount of data buffered to the first buffer 310 also begins to decrease, so that the buffer 3iG will be cleared at time Τ4 because there is no The data continues to slow down to the first buffer S 310, so the data burning process will be at time A = and the optical storage device 350 will be followed by a connection point, as described above, '=Save M35G data burning speed is It is much faster than the multimedia data to generate the data generation speed of the 3 milk. Therefore, at time 5, the optical storage data is stopped (4) burning the multimedia data generating device 34G to generate the data 2:, and the data storage control unit 331 The received input "in is buffered to the currently vacant first buffer 310. As shown in Fig. 5, 'filling in the second buffer 32(), before the value, the f-buffer 310 will first fill up to the first critical value, and: 1293172 is only in the first buffer 310 and the second buffer. After the data is filled to the respective thresholds, the data burning process will be started. Therefore, during each data burning period, the total amount of burning data is much larger than that of the prior art, because the first buffer Both the device 310 and the second buffer 320 are fully utilized, so that the number of connection points can be reduced and the overall data burning performance can be greatly improved. Please note that the quality of the multimedia material (for example, HQ, SP, LP, EP, SLP, SEP) determines the data generation speed, that is, the input data speed of the second buffer 32〇 depends on the multimedia material generating device 340. The quality of the multimedia material, and when the data generation speed is slow, then the buffer space reserved for error handling (errorhandling) can also be reduced, so the first critical value and the first 63⁄4 boundary value can be set to a larger value. Therefore, the number of joint points is further reduced. Therefore, the threshold value provider can arrange the required threshold according to the multimedia material quality (e.g., HQ, Sp, Lp, Ep, SLP, SEP) of the multimedia data generating device 340, so as to achieve the best performance. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should fall within the scope of the present invention.
